Another killer pattern from John Barr, this fly incorporates a tungsten bead and elements from the Copper John, Prince Nymph and Hare's Ear. Can appear as a large mayfly nymph or a smaller stonefly nymph. A great dropper fly to be used as weight to get deep with smaller/lighter weight flies.
The Tung Teaser pattern is especially productive during low light hours when nymphs are redistributing themselves during natural behavioral drift cycles and are exposed to trout. These cycles are heaviest during spring and fall months.
On rivers that contain large populations of stoneflies, this fly imitates the sizes of stonefly nymphs that are most prevalent in the drift.
